SIDE BEND TEST

SIDE BEND TEST

Object: To determine the soundness of the weld metal and HAZ in a cross section. This may be preferred to the transverse bend test on thick materials. It is also used on processes or procedures expecting lack of fusion (e.g. thick plate using MIG).

Method: The testing method is the same as that used for transverse bends except the cap and root are not ground flush, to allow testing across the complete weld.

Report Results:
  1. Width and thickness of specimen. 
  2. Angle of bend.
  3. Diameter of former.
  4. Appearance of joint after bending e.g. type and location of flaws.

Part -5 Most commonly asked Mechanical Interview Questions

Most commonly asked Mechanical Interview Questions with answer 1. Why the Centrifugal Pump is called High Discharge pump? Ans. Centrifugal pump is a kinetic device. The centrifugal pump uses the centrifugal force to push out the fluid. So the liquid entering the pump receives kinetic energy from the rotating impeller. The centrifugal action of the impeller accelerates the liquid to a high velocity, transferring mechanical (rotational) energy to the liquid. So it discharges the liquid in high rate. It is given in the following formulae: Centrifugal force F= (M*V2)/R. Where, M-Mass V-Velocity R-Radius 2. How Cavitation can be eliminated by Pump? Ans. Cavitation means bubbles are forming in the liquid. To avoid Cavitation, we have to increase the Pump size to One or Two Inch To increase the pressure of the Suction Head  Decrease the Pump Speed. 3. Why Cavitation will occur in Centrifugal Pump and not in Displacement Pump? Ans. The form...

VISUAL INSPECTION OF WELDING

VISUAL  INSPECTION OF WELDING INTRODUCTION Inspection starts with examination of the material prior to fabrication, scabs, seams, scale or other harmful surface conditions may be detected in visual inspection. The inspector should check the following : Weld preparation, dimensions and finish.  Clearance dimensions of backing strips.  Alignment and fit up to the pieces being welded.  Verification of cleanliness.  Visual Inspection During Welding Visual inspection checks details of the work while welding is in progress. Among the details to be checked are : Welding process.  Cleaning.  Preheat and inter pass temperature.  Joint preparation.  Filler metal.  Flux or shielding gas.  Chipping, grinding, or gouging.  Post heating temperature and time.  Visual Inspection After Welding Visual inspection is useful for finished-product verification of such items as : Profile irregularities of the weldment....

Part -8 Most commonly asked Mechanical Interview Questions

Most commonly asked Mechanical Interview Questions  ·          What happens if gasoline is used in a Diesel engine?Diesel engine will work ? No, It will not work,as the Compression ratio of Petrol engine is 6 to 10 & that of Diesel engine is 15 to 22 . Thus on such high compression, gasoline gets highly compressed & it may blast. ·          Which Mechanism is used in Automobile gearing system Differential mechanism ·           Why different types of sound are produced in different bikes though they say run on SI engine Engine specifications are different in different manufactures like as Bore Diameter(CC), Ignition timing.Also the exhaust passage take more responsible for sound. ·           Why entropy decreases with the increase in temperature? ds=dQ/T Entropy is inversely proportional to the temperatu...
